We're going to be traveling abroad next month and I've heard enough horror stories about people getting socked with huge bills that I'm trying to disable charged international roaming. I see there are short codes #763# (off) and #766# (on) to toggle this?
When I use #763#, I get: "SQL Error". For #766# I get "Prepaid Service Not Available!" (Do these codes only work for prepaid?)
Anyway, I wonder if I'm doing anything wrong, or if this is irrelevant with my plan (Magenta Max 55). I have an iPhone SE 2nd Gen, if it matters.
(I also know there is a profile setting on the web site, which we're set to enable roaming but disable charged roaming. Just wondering if this should be working, too.)
